GSK recalls nearly 600,000 asthma inhalers due to leaks

The affected lot numbers are 6ZP0003, 6ZP9944 and 6ZP9848, according to CNN. The devices were recalled from hospitals, pharmacies, retailers and wholesalers in the United States.

The defect does not make the product dangerous to users, but it might not provide as many doses of the medicine as promised.

GSK said users whose symptoms are not relieved by the inhalers should seek medical treatment.
